IMPROVEMENT IN PEN-HOLDING PENCIL-POINT PROTECTORS.

Specification forming part of Letters Patent No. 175,754, dated April 4,1876 application filed February 2, 1876.

To all whom it may concern:

Be it known that we, J QSEPH REcKEN- DORFER and HELLMUTH M. PALLESKE,both of the city, county, and State of New" York, have invented certainnew and useful Improvements in Combined Pen Holders and Pencil-PointProtectors, of which the following is a specification:

Our invention is designed to combine in one device a pen-holder and apencil'point protector. The main feature of our invention is apen-holding tube provided at one end with a pen-holding device, andsplit from the other end for a portion of its length, in order to makeof this portion an elastic and expansible tube, which will fit and claspthe end of an ordinary lead-pencil inserted therein.

Minor features of our invention will appear in the description, which weshall now proceed to give of the manner in which our invention is or maybe carried into effect by reference to the accompanying drawing, inwhich- Figure l is a perspective view of a device embodying ourinvention. Fig. 2 is a longitudinal central section of the same.

In each figure the device is represented applied to a pencil.

A is the point-protecting tube. This tube, for a portion of its lengthonly, is slit, as seen at a, the length of the slit being the extent towhich the cylindrical body of the pencil B can enter the tube. Thisportion of the tube is formed in the manner just described, in order togive it the springiness and expansibility needed in order to permit itto receive and clasp the pencil. The tube for the re mainder of itslength is unbroken, the length of this portion being suflicient toreceive a surrounding sleeve, 0, which is movable longitudinally on thesaid portion of the tube. Within the tube A is a split spring'barrel, D,(shown detached in Fig. 3,) such as used in pen-holders to retain thepen. The pen bis inserted andheld between the barrel D and -tube A. Thesliding sleeve is designed to cover and protect the pen when the latteris,

not in use. In this instance it is guided and limited in its movement bya stud or pin, a, which serves to rivet together the barrel and thetube, and which projects into longitudinal slot at in the sleeve.

Under the arrangement described the pointprotecting tube is openinteriorly from end to end, including the pen-holding part, so thatthere is no obstruction offered to the pencil-point, which, of course,projects into the tube much farther than the-pencil-body. The sleevemaybe held to and arranged to move on the tube in various ways, all thatis needed being that it should have suflicient longitudinal movement touncover .or cover the pen, as occasion demands, and that the range ofits movement should be confined, substantially, to the unsplit length ofthe tube, so as not to cramp or materially bind the expansive portion ofthe tube.

We do not broadly claim combining a protecting sleeve with apencil-point protector. This is not new with us.

In Figs. 4: and 5 a modification of our invention is shown. Fig. 4 is alongitudinal central section of the pen holder and pointprotector, andof the pencil to which the same is applied. Fig. 5 is'a perspective viewof the pen-holder and point-protector detached.

The tube A in this device is constructed for the most part as is thetube A shown in the preceding figures. We here dispense, how ever, withthe sleeve 0, and at or near the pencil-receiving end of the tube weform an annular groove, f, in the interior of the tube, which, when thepencil is inserted in the tube, snaps 'over an annular rib, g, on thepencil, and thus serves, in conjunction with the rib, to lock the twoparts together.

The pencil here shown is one that has a removable lead, and is provided,as usual, with a sheet-metal screw cone, h, which can be screwed in onedirection or the other, to compress the pencil-jaws or relax the hold ofthe same on the lead. The rib g is formed on the cone h. If-desired, therib can be on the tube and the groove in the cone. This arrangement isapplicable to pencil-point pro tectors generally. v

Having described our invention, what we claim, and desire to secure byLetters Patent,

is as follows:

1. A combined pen-holder and pencil-point protector, consisting of asheet-metal tube, having at one end a pen-holding device, and split foraportieu of its length only from its other end, to adapt it to fit andclasp the end of an ordinary lead-pencil.

2. A pencil-point protecting tube split for a portion of its lengthonly, and provided at the split end with an annular groove, incombination with a pencil having an annular rib or projection, whichengages the groove when the pencil and tube are fitted together,substantially as set' forth.

3. The pen-holding and pencil-point-protecting tubesplit from the endopposite the pen- .holder for a portion of its length only, asdescribed, in combination with a sleeve mounted and movablelongitudinally on the unsplit portion of the tube, substantially as andfor the purposes set forth.

In testimony whereof we have hereunto signed our names this 29th day ofJanuary, A. D. 1876.
